Hey, ironbear..if you'd be willing to connect, I'd love to chat...it's hard to put into words what that time of my life was like, and it's very, very cool to hear about stuff that I grew up with in my basement being used for other great broadcast purposes...this was intended to be edited, but the webmaster posted the whole thing...brief synopsis of the 70's time line of KBAZ/KZMK. As I remember it, KSUN's owner did have the original c.p. for 92.1...but let it lapse, and that's when my dad came in.

I still have all of the FCC files and records...
So...you bought the equipment from Casto, the GM, or the engineer??? Yup, my dad picked out the xmtr site, one of the highest points (highest?) in Cochise County...50 watts did a lot of damage at that altitude
Future owners sold/traded the 92.1 to 92.3 to make a buck..ironically to/with the same Tucson group I'd end up spending most of my career with...maybe my dad would have done the same thing.
Not sure if you can see this, but here's a link to the newspaper article when we (Copper Valley) were first up and running:
